#extension GL_ARB_compute_shader : enable Once again, the test worked perfectly fine on the HD 7970 (Win8) and HD 7770 (Linux Mint 15). The second compute shader test (GLSL_Compute_Shaders_Particles/) deforms a grid of vertices using some sin+cos functions. The test worked fine with HD 7970 (Win8) and HD 7770 (Linux Mint 15). The first compute shader test (GLSL_Compute_Shaders_PostFX/) performs a post processing effect and uses the imageStore() function to write the new data into the destination texture. For the tests, I used GLSL Hacker and loaded two demos of the Code Sample Pack: GLSL_Compute_Shaders_PostFX/ and GLSL_Compute_Shaders_Particles/. ![]() ![]() I did two tests: one under Windows 8 64-bit with a Radeon HD 7970 and a second under Linux Mint 15 with a Radeon HD 7770. With the release of a new graphics driver with full OpenGL 4.3 support by AMD for Windows and Linux, I couldn’t resist to test compute shaders, one of the media features of OpenGL 4.3.
